The only challenge I’ve got with it is that the logo isn’t responsive when the browser window is narrowed. Full screen on a PC and the logo is fine. On an iPhone or other smartphone, the logo is cropped on the right hand side, leaving only the left hand half visible.

When, you scroll down the page, the logo / header shrinks in size which is perfect. However, the logo doesn’t shrink in size when the browser window is made narrower.
